What concepts? I'm talking about physical cash, paper banknotes, Benjamins. You're saying people without Internet don't understand the concept of cash?
I don't have a patronizing attitude toward people just because they aren't able to access or afford modern technology. People all over the world know how to take advantage of USD cash. If they had access to BTC cash that held value against their local fiat scrip as well as or better than the USD, and was also universally accepted by local money changers like USD cash, I'm sure most people would be capable of grasping that concept.
